RESUMEN

Micromeria biflora (M.B) Benth has proven anti-inflammatory efficacy, thereby, the goal of the current investigation was to assess the anti-arthritic potential of M.B ethanolic extract and fractions as well as to investigate the likely mechanism of action. The effectiveness of M.B against acute arthritic manifestations was assessed using an arthritic model prompted by formaldehyde, whereas a chronic model was developed using an adjuvant called Complete Freund's in Sprague-Dawley rats. Weekly evaluations were conducted for parameters involving paw volume, body weight, and arthritic score; at the completion of the CFA model, hematological, biochemical and oxidative stress parameters as well as the level of various mediators (PGE2, IL-1ß, TNFα, IL6, MMP2, 3, 9, VEGF, NF-ĸB, IL-10, and IL-4) were evaluated. The results demonstrated the plant's ability to treat arthritis by showing a significant decrease in paw volume, arthritic score, and histological characteristics. The levels of NF-ĸB, MMP2, 3, 9, IL6, IL1ß, TNFα, and VEGF were all significantly reduced after treatment with plant extract and fractions. Plant extract and its fractions substantially preserved body weight loss, oxidative stress markers and levels of IL-4 and 1L-10. PGE2 levels were also shown to be reduced in the treatment groups, supporting the M.B immunomodulatory ability. Hematological and biochemical indicators were also normalized after M.B administration. Outcomes of the study validated the anti-arthritic and immunomodulatory attributes of M.B probably through modulating oxidative stress, inflammatory, pro-inflammatory and anti-inflammatory biomarkers.

RESUMEN

The monoterpene oxide, Eucalyptol (1,8-Cineole), a primary component of eucalyptus oil, has been evaluated pharmacologically for anti-inflammatory and analgesic activity. Current research aimed to evaluate Eucalyptol's anti-arthritic potential in a Complete Freund's adjuvant induced arthritis that resembles human rheumatoid arthritis. Polyarthritis developed after 0.1 mL CFA injection into the left hind footpad in rats. Oral administration of Eucalyptol at various doses (100, 200 and 400 mg/kg) significantly reduced paw edema, body weight loss, 5-LOX, PGE2 and Anti-CCP levels. Real-time PCR investigation showed significant downregulation of COX-2, TNF-α, NF-κB, IL-17, IL-6, IL-1ß and upregulation of IL-4 and IL-10 in Eucalyptol treated groups. Hemoglobin and RBCs counts significantly increased post-treatment with Eucalyptol while ESR, CRP, WBCs and platelets count significantly decreased. Eucalyptol significantly increased Superoxide Dismutase, Catalase and Glutathione levels compared to CFA-induced arthritic control however, MDA significantly decreased post-treatment. Further, radiographic and histopathological examination of the ankle joints of rodents administered Eucalyptol revealed an improvement in the structure of the joints. Piroxicam was taken as standard. Furthermore, molecular docking findings supported the anti-arthritic efficacy of Eucalyptol exhibited high binding interaction against IL-17, TNF-α, IL-4, IL-10, iNOS NF-κB, 5-LOX, and COX-2. Eucalyptol has reduced the severity of CFA induced arthritis by promoting anti-inflammatory cytokines for example IL-4, IL-10 and by inhibiting pro-inflammatory cytokines such as 5-LOX, COX-2, IL-17, NF-κB, TNF-α, IL-6 and IL-1ß. Therefore, Eucalyptol might be as a potential therapeutic agent because of its pronounced anti-oxidant and anti-arthritic activity.

RESUMEN

Because of evident role of renin-angiotensin system in the etiology of rheumatoid arthritis, the current study's objective was to assess the anti-arthritic efficacy of ramipril through CFA-instigated arthritic model. The drug has been shown to have anti-inflammatory potential. CFA-instigated arthritic model assessed the anti-arthritic efficacy of ramipril by estimating different parameters, including paw volume, arthritic index scoring, haematological and biochemical attributes, histological and radiographic analyses, and various cytokines level. Ramipril significantly (p < 0.001) reduced paw volume and the arthritic index especially at the dose of 4mg/kg. The biochemical and haematological changes were likewise restored to normal by ramipril administration with an increase in anti-inflammatory cytokines while reducing pro-inflammatory cytokines level. Ramipril's ability to prevent arthritis by preserving the normal architecture of arthritis-induced joints is further supported by radiographic and histological investigation. The study's findings demonstrated ramipril's considerable anti-arthritic activity. To identify the precise mechanism of action, however, thorough mechanistic studies are still needed.

RESUMEN

Enalapril with documented anti-inflammatory potential was evaluated in current investigation to explore its anti-arthritic efficacy. For anti-arthritic evaluation of enalapril, CFA-instigated arthritic model was employed after which various parameters comprising paw volume, body weight, arthritic index, hematological and biochemical parameters, radiographic analysis and level of various cytokines were estimated. Enalapril demonstrated significant (p˂0.001) anti-arthritic activity by suppressing paw volume, arthritic index while preserved CFA instigated weight loss. Likewise, enalapril also normalized the hematological and biochemical alterations, suppressed the level of proinflammatory cytokines with elevation of anti-inflammatory cytokines. Radiographic and histopathological analysis also further validates the anti-arthritic attribute of enalapril where enalapril preserved the normal architecture of arthritis induced joints. Outcomes of the study pointed out a notable anti-arthritic activity of enalapril. However detailed mechanistic studies are still required to point out the exact mechanism of action.

RESUMEN

Acacia Nilotica (AN) has long been used as a folk cure for asthma, but little is known about how AN could possibly modulate this disease. Thus, an in-silico molecular mechanism for AN's anti-asthmatic action was elucidated utilizing network pharmacology and molecular docking techniques. DPED, PubChem, Binding DB, DisGeNET, DAVID, and STRING were a few databases used to collect network data. MOE 2015.10 software was used for molecular docking. Out of 51 searched compounds of AN, eighteen compounds interacted with human target genes, a total of 189 compounds-related genes, and 2096 asthma-related genes were found in public databases, with 80 overlapping genes between them. AKT1, EGFR, VEGFA, and HSP90AB were the hub genes, whereas quercetin and apigenin were the most active components. p13AKT and MAPK signaling pathways were found to be the primary target of AN. Outcomes of network pharmacology and molecular docking predicted that AN might exert its anti-asthmatic effect probably by altering the p13AKT and MAPK signaling pathway.

RESUMEN

Terpinen 4-ol, a phytochemical is a monoterpene which has been reported for its anti-inflammatory effect. Present research was planned to check its effect against arthritis through in vitro and in vivo models. Terpinen 4-ol was evaluated through in-vitro procedures including blocking of protein (BSA and egg albumin) denaturation and human RBC membrane stabilization. In in vivo study, terpinen 4-ol (15, 30 and 60 mg/kg) was evaluated using formaldehyde and CFA arthritic models. Terpinen 4-ol significantly inhibited increase in paw and joint swelling as compared to diseased group. Terpinen 4-ol showed remarkable antioxidant effect (SOD, reducing power) and also improved body weight, haematological, histopathological and radiological parameters in CFA model. Also, moreover, the excess production of IL-1ß, TNF-α, IRAK, and NF-kB were noticeably attenuated in all terpinen 4-ol treated rats, however, IL-17 and IL-10 were distinctly increased compared to arthritic control rats in RT-PCR. Also, terpinen 4-ol showed promising antioxidant effect in DPPH assay. Henceforth, it might be concluded that terpinen 4-ol has anti-arthritic effect which can be attributed to the downregulation of pro-inflammatory cytokines.

RESUMEN

Ranunculus muricatus (Ranunculaceae) is commonly used by inhabitants of Pakistan for the treatment of gout and rheumatism, both of which are inflammatory disorders. The present study attempts to evaluate the anti-inflammatory and analgesic activities of aqueous methanolic extract of R. muricatus in mice. The plant extract at doses of 50, 100 and 150 mg/kg was tested for anti-inflammatory activity against carrageenan and egg albumin induced paw edema in mice and analgesic activity was appraised against acetic acid induced writhing and formalin induced paw licking in mice models. The results designate that extract at the highest dose of 150 mg/kg significantly (p<0.001) and dose dependently inhibited carrageenan induced and egg albumin induced paw edema. Similarly, extract at the same dose of 150 mg/kg showed potent and dose dependent (p<0.001) suppression of formalin induced paw licking and abdominal constrictions / stretching of hind limbs induced by acetic acid. The anti-inflammatory and analgesic activity of plant extract was comparable to standard drug ibuprofen in all models. This study thus supports the use of R. muricatus in traditional medicine for conditions associated with inflammation and analgesia which might be attributed to its previously proven high alkaloid, flavonoids, phenol, tannins content and free radical scavenging activity.

RESUMEN

World Health Organization (WHO) estimated breast cancer as one of the most prevailed malignancy around the globe. Its incident cases are gradually increasing every year, resulting in considerable healthcare burden. The heterogeneity of breast cancer accounts for its differential molecular subtyping, interaction between pathways, DNA damaging, and chronic inflammation. Matrix metalloproteinases (MMPs) are a group of zinc-containing, calcium dependent endopeptidases which play a substantial role in breast carcinogenesis through several mechanisms. These mechanisms include remodeling of extracellular matrix (ECM), cell proliferation, and angiogenesis which promote metastasis and result in tumor progression. In this context, compounds bearing MMP inhibitory potential can serve as potent therapeutic agents in combating MMPs provoked breast cancer. Current systematic review aimed to encompass the details of potent natural lead molecules that can deter MMPs-provoked breast cancer. Following the critical appraisal of literature, a total of n = 44 studies that explored inhibitory effect of phytochemicals on MMPs were included in this review. These phytoconstituents include alkaloids (n = 11), flavonoids (n = 23), terpenoids (n = 7), and lignans (n = 2). The most common inhibitory methods used to evaluate efficacy of these phytoconstituents included Gelatin Zymography, Western Blotting, and real time polymerase chain reaction (RT-PCR) analysis. Moreover, current limitations, challenges, and future directions of using such compounds have been critically discussed. This review underscores the potential implications of phytochemicals in the management of breast cancer which could lessen the growing encumbrance of disease.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: The roots of Ribes orientale (Family Grossulariaceae) have long been used as a folk remedy to treat rheumatism and joints pain in Northern Areas of Pakistan. AIM OF THE STUDY: The purpose of study was to observe the preventive efficacy of roots of Ribes orientale (RO) aqueous ethanolic extract (30:70) and its aqueous and n-butanol fractions in treating rheumatoid arthritis and to determine its possible mechanism of action. MATERIAL AND METHODS: Arthritis was evaluated in vitro using heat induced bovine serum albumin and egg albumin denaturation and membrane stabilizing assays at 50-6400 µg/ml concentration of extract/fractions whereas, in vivo arthritis was evaluated at 50, 100, 200 mg/kg doses of extract/fractions in formaldehyde model by measuring rat paw volume/diameter. Moreover, highest effective dose (200 mg/kg) of extract/fractions was evaluated in Freünd complete adjuvant (FCA) model. Arthritis was induced in Sprague Dawley rats by immunization with 0.1 ml FCA in left footpad. RO extract/fractions at 200 mg/kg were orally administered from day 0, 30 min prior to adjuvant injection and sustained for 28 days. Paw volume/diameter, arthritic score, body weight, and hematological (WBC, RBC, ESR, Hb and Platelet count) and biochemical (AST, ALT, ALP, urea, creatinine, CRP and RF) parameters were observed. The mRNA expression levels of COX-2, IL-1ß, IL-6, NF-kB, TNF-α, IL-4 and IL-10 were measured by real time reverse transcription polymerase chain reaction (RT-PCR) whereas, PGE2 and TNF-α levels in serum samples were measured by Enzyme linked immunosorbent assay (ELISA). Furthermore, radiographs of hind paws and histological changes in ankle joint were analyzed in adjuvant injected rats. The anti-oxidant activity of plant extract and fractions was evaluated using DPPH and reducing power assays. In addition, phytochemistry, total phenolic and flavonoid contents, and HPLC analysis of most active fraction (aqueous fraction) were performed. RESULTS: Results showed that RO extract and fractions (notably aqueous fraction) significantly reduced protein denaturation and protected erythrocyte membrane in concentration dependent manner. Similarly, extract/fractions induced dose-dependent decrease in paw volume/diameter in the formaldehyde model. Plant extract and fractions significantly suppressed paw swelling and arthritic score, prevented cachexia and remarkably ameliorated hematological and biochemical changes. Furthermore, RO extract/fractions downregulated gene expression levels of PGE2, COX-2, IL-1ß, IL-6, NF-kB and TNF-α whereas, upregulated those of IL-4 and IL-10, compared with FCA control rats. The radiographic and histopathologic improvement in joint architecture was also observed in RO treated rats. Piroxicam, used as reference drug, also significantly suppressed arthritis. Additionally, plant exhibited notable anti-oxidant activity and phytochemical analysis revealed the presence of flavonoids and polyphenols. CONCLUSION: Results indicated that suppression of pro-inflammatory enzymes/cytokines, inhibition of protein denaturation, lysosomal membrane stabilizing abilities, and redox/free radical scavenging properties of RO extract and fractions support anti-arthritic and immunomodulatory property of Ribes orientale that might be due to its polyphenolic and flavonoid constituents. This suggests that Ribes orientale roots may be used as a therapeutic agent for treating human arthritis.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: The whole plant, roots and stems of Ephedra gerardiana (Family Ephedraceae) have long been used as a folk remedy to treat rheumatism and painful joints in Northern Areas of Pakistan. AIM OF THE STUDY: The purpose of study was to observe the preventive efficacy of Ephedra gerardiana (EG) aerial parts in treating rheumatoid arthritis using Freund's complete adjuvant (FCA) induced arthritis in rat model and to determine its possible mechanism of action. MATERIAL AND METHODS: Arthritis was induced in Sprague Dawley rats by immunization with 0.1 ml FCA in left footpad. EG aqueous ethanolic extract (30:70) and its aqueous, n-butanol and ethyl acetate fractions at 200 mg/kg were orally administered from day 0, 30 min prior to adjuvant injection and sustained for 28 days. Paw volume/diameter, arthritic score, body weight, and hematological (WBC, RBC, ESR, Hb and Platelet count) and biochemical (AST, ALT, ALP, urea, creatinine, CRP and RF) parameters were observed. The mRNA expression levels of COX-2, IL-1ß, IL-6, NF-kB, TNF-α, IL-4 and IL-10 were measured by real time reverse transcription polymerase chain reaction (RT-PCR) while, PGE2 and TNF-α levels in serum samples were measured by Enzyme linked immunosorbent assay (ELISA). Moreover, radiographs of hind paws and histological changes in ankle joint were analyzed in adjuvant injected rats. In addition, anti-oxidant activity of plant extract and fractions was also evaluated using DPPH and reducing power assays. Also, preliminary phytochemistry and total phenolic and flavonoid contents were investigated in most active fraction (aqueous fraction). RESULTS: EG extract and fractions (notably aqueous fraction) significantly suppressed paw swelling and arthritic score, prevented cachexia and remarkably ameliorated hematological and biochemical changes. Furthermore, the overproduction of PGE2, COX-2, IL-1ß, IL-6, NF-kB and TNF-α were remarkably attenuated in all EG treated rats, however, IL-4 and 10 were markedly increased. The radiographic and histopathologic improvement in joint architecture was also observed in EG treated rats. Piroxicam, used as reference drug, also significantly suppressed arthritis. Additionally, plant exhibited notable anti-oxidant activity and phytochemical analysis revealed the presence of alkaloids, flavonoids, phenols, tannins, saponins and glycosides. CONCLUSION: These results indicate that EG extract and fractions significantly attenuated adjuvant arthritis in rats by decreasing the levels of aforementioned pro-inflammatory and increasing the levels of anti-inflammatory mediators. This suggests that Ephedra gerardiana aerial parts might be used as a therapeutic agent for treating human arthritis.

RESUMEN

BACKGROUND: The roots and stem bark of Berberis orthobotrys (Berberidaceae) have long been used traditionally to treat joint pain. Though, it has not been pharmacologically assessed for rheumatoid arthritis. The current study explores anti-arthritic activity and phytochemical analysis of aqueous-methanolic extract (30:70) and fractions (ethyl acetate, n-butanol, and aqueous) of Berberis orthobotrys roots. METHODS: Anti-arthritic potential was evaluated in vitro using protein denaturation (bovine serum albumin and egg albumin) and membrane stabilization methods at 12.5-800 µg/ml concentration and in vivo via turpentine oil, formaldehyde and Complete Freund Adjuvant (CFA) models at 50, 100 and 150 mg/kg doses. Also, in vitro antioxidant ability was appraised by reducing power assay. Moreover, total flavonoid content, Fourier transform infrared spectroscopy and High performance liquid chromatography of n-butanol fraction were performed. RESULTS: The results revealed concentration dependent inhibition of albumin denaturation and notable RBC membrane stabilization, with maximum results obtained at 800 µg/ml. Similarly, plant exhibited dose dependent anti-arthritic effect in turpentine oil and formaldehyde models, with maximum activity observed at 150 mg/kg. The results of CFA model depicted better protection against arthritic lesions and body weight alterations. Also, B.orthobotrys remarkably ameliorated altered hematological parameters, rheumatoid factor and positively modified radiographic and histopathological changes. Additionally, plant exhibited remarkable anti-oxidant activity. Moreover, phytochemical analysis revealed polyphenols and flavonoids. CONCLUSION: Taken together, these results support traditional use of B.orthobotrys as potent anti-arthritic agent that may be proposed for rheumatoid arthritis treatment.

RESUMEN

CONTEXT: Cuscuta reflexa Roxb. (Cuscutaceae) has been used traditionally for treating sore knees and kidney problems, but its efficacy has not been scientifically examined in treating arthritis and nephrotoxicity. OBJECTIVE: Present study determines antiarthritic and nephroprotective potential of the aqueous methanolic extract of Cuscuta reflexa (AMECR). MATERIALS AND METHODS: Antiarthritic activity of Cuscuta reflexa in formaldehyde and turpentine oil-induced rat arthritis models was appraised at 200, 400 and 600 mg/kg doses for 10 days and 6 h period, respectively, and in vitro protein denaturation (bovine serum albumin, egg albumin) inhibition was studied at 25-800 µg/mL concentration. The nephroprotective effect involved gentamicin-induced nephrotoxicity in rats at 200, 400 and 600 mg/kg doses. RESULTS: Plant extract at 600 mg/kg significantly reduced paw oedema and joint swelling with maximal inhibition of 71.22% at the 6th hour for turpentine oil and 76.74% on 10th day for formaldehyde. Likewise, in vitro results corroborated significant concentration-dependent increase in percentage protection at 800 µg/mL against both bovine serum albumin (89.30%) and egg albumin (93.51%) denaturation. Similarly, 600 mg/kg dose showed maximum nephroprotection by reducing serum urea (41.400 ± 0.510 mg/dL), uric acid (0.740 ± 0.032 mg/dL), blood urea nitrogen (18.370 ± 0.328), creatinine (3.267 ± 0.076) and minimizing kidney weight gain (0.586 ± 0.005) and histopathological alterations on 8th day. Furthermore, phytochemical and HPLC analysis revealed the presence of important phytoconstituents. DISCUSSION AND CONCLUSIONS: These results suggest that AMECR provides protection against arthritis and nephrotoxicity that might be due to the existence of phytoconstituents, thus supporting folkloric claim.

RESUMEN

Hepatic diseases are becoming common day by day and pose serious health threats to the life of humans. In order to treat these diseases, the attention of man is diverting towards herbal drugs, which are much safer and cost effective than synthetic drugs. The aim of present study was to investigate hepatoprotective activity of methanolic extract of Melilomus officinalis against paracetamol and carbon tetrachloride induced hepatic damage. Melilotus officinalis at selected oral doses of 50 mg/kg and 100 mg/kg showed significant hepatoprotective effects by decreasing the levels of serum marker enzymes such as total bilirubin, SGOT, SGPT, ALP, albumin and total protein, when compared with standard drug (silymarin) and negative control. Similarly, histopathological studies also supported biochemical estimations. It was concluded that extract of Melilotus officinali has strong hepatoprotective activity against paracetamol and carbon tetrachloride induced hepatotoxicity, which might be due to free radical scavenging mechanisms exhibited by flavonoids and phenolics, thus affirming its traditional therapeutic role in liver injury.

RESUMEN

The current study was conducted to evaluate the anti-diabetic effect of polyherbal product "diabetic bal" in normal and alloxan induced diabetic rabbits. Glibenclamide was used as standard drug. Diabetes was induced by single i.v. injection of 150 mg/kg b.w. of alloxan monohydrate in rabbits. "Diabetic bal" (250 and 500 mg/kg) significantly decreased the blood glucose level both in normal and diabetic rabbits in dose dependent manner. In oral glucose tolerance test, "Diabetic bal" demonstrated a significant inhibitory effect on rise of blood glucose level compared to control. "Diabetic bal" showed synergistic anti-hyperglycemic effect with dif- ferent units of insulin in diabetic rabbits. The "diabetic bal" decreased the glucose level and prevented the weight loss of diabetic rabbits as compared to control for an extended period of one month. It caused a significant increase (p < 0.001) in the insulin level of treated diabetic rabbits in 30 days study. In addition AST, ALT, ALP, cholesterol, LDLs, VLDLs and triglyceride level were significantly reduced whereas HDLs level was sig- nificantly elevated in diabetic rabbits with 500 mg/kg dose. The herbal product did not cause any significant change in CBC as compared to normal control in diabetic rabbits for one month. It is conceivable; therefore, that "diabetic bal" is effective in diabetes and its associated complications which support its use in folklore.
